On our 6-oz., 32-oz., and 64-oz. cups you will find a "BEST BY" date printed on each lid, which refers to the expiration date. If refrigerated properly, we guarantee the yoghurt's quality up to this date. If opened before the expiration date, please keep the yoghurt refrigerated and consume it within 10 days. After those 10 days or after the expiration date, the yoghurt is past its expiration and should be discarded. We recommend writing the date you opened it on the lid so that you know.

and from the Cascade Fresh yogurt website:>>>What does the code date on the side of the container signify?

The code date on the container is the sell by date. This is the date when the cultures slowly start to diminish. To get the maximum benefit from the live cultures our products should be eaten by the code date and should be refrigerated until eaten. However, because of the live cultures, yogurt is also a very safe food. All our Cascade Fresh products are good to eat past the sell by date. Traditionally cultures were used to preserve milk and cultured products are not like milk or meat that can spoil by their expiration date. Live active cultures retard colonization of putrefactive bacteria, such as E. coli and Salmonella that can make you ill.

Some yogurts without the thickeners and stabilizers added will separate and that is fine, just stir it back. And of course only use a clean utensil if you scoop out of a larger tub size. You can also freeze yogurt but the texture changes up a bit when thawed. It is good to eat frozen or partially frozen but you lose some of the active cultures when frozen and that is why I eat yogurt...for the live cultures.
